The position of an object moving along a line is given by #p(t) = t - 3sin(( pi )/3t) #. What is the speed of the object at #t = 4 #?
1 Answer
(1)+(2)
Now it depends on the extra information given:
1.If the acceleration isn't constant:
Using the law of space for the varied linear uniform movement:
where
Assuming that the initial speed of the object is
Finally the speed of the object at t=4 is
2.If the acceleration is constant:
With the law of linear uniform movement:
You will get:
